The most energy efficient exterior doors are typically made from materials such as fiberglass and steel, which provide excellent insulation. Fiberglass doors are particularly popular because they resist warping and have a high R-value, which measures thermal resistance. On the other hand, steel doors, when properly insulated, can also keep your home comfortable while saving on energy costs.Fiberglass Exterior DoorsFiberglass doors offer a fantastic balance between durability and efficiency. They can mimic the appearance of wood without the maintenance issues associated with it. A properly installed fiberglass door can minimize air leaks, keeping your home cozy during the winter and cool in the summer. Plus, these doors can come with Energy Star ratings, ensuring they meet strict energy efficiency guidelines.Steel Exterior DoorsSteel doors are another top contender for energy efficiency. They are often filled with foam insulation, which significantly reduces heat transfer. Additionally, steel doors are known for their security features and resistance to dents. However, it’s essential to choose a steel door with a high-quality weather stripping to prevent any drafts.Factors to ConsiderWhen selecting an energy efficient exterior door, consider the following factors: the door’s material, insulation type, energy ratings, and installation quality. Don’t forget to check for a solid warranty, which can reflect the door's durability and performance. Remember, even the best door won’t perform well if not installed correctly!FAQHave you considered what material your next exterior door will be?
